CSS border-block-end-style
The border-block-end-style property is used to set the style of the border on the end side of a block-level element. The end side is determined by the writing mode (horizontal or vertical) of the document.
The possible values for border-block-end-style are the same as for the border-style property: none, hidden, dotted, dashed, solid, double, groove, ridge, inset, and outset.
Here's an example of how you can use the border-block-end-style property in your CSS:
.example {
border-block-end-style: dotted;
}
In the example above, we set the border-block-end-style property of an element with the class example to dotted, which will make the border on the end side of the element a dotted line.
